Consider two different processes (a) you are preparing for a bike race, and you note that the pressure in your tires is only 80 psi (5 atmospheres). for optimal performance, however, you want your tires to be at 160 psi. when you inflate the tire with a hand pump, the temperature inside the tire rises. (you can only really feel the warming effect at the metal valve stem since the rubber in the tire and tube is a good insulator.) (b) artificial snow is made by quickly releasing a mixture of compressed air and water at about 20 atm from a snow making machine to the surroundings. explain these results two different ways: (1) in terms of the first law of thermodynamics, and: (2) in terms of the ideal gas equation, assuming air behaves like an ideal gas.
